1 Claim. 1

This invention relates to certain. new and use.- ful: improvements inbuilding blocks especially adaptable for the construction of buildingsof various descriptions... such. as homes, lofts, and the like.

Theinvention has as a principal object the provision of a, constructionof, this character which will be highly efficient in.use,. andeconomical in manufacture.

One of the prime objects of this invention is to provide a buildingblock which may be preformed prior to installation and which, whencomplete, will be of relatively light weight, thereby facilitatingmoving and installation.

Yet another and equally important object of this invention is to providebuilding blocks which when fitted together to form a wall, provide ahighly insulated wall having the maximum degree of soundproofness, andone which will be substantially fireproof, termite-proof and earthquakeresisting, and a wall which may. be constructed without the costlynecessity of forming the columns of wood or steel and then binding thebuilding units to these structural columns.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of partsto be hereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings showing the preferred form of construction, and in which:

Fig. 1 is a fragmentary perspective View of a wall constructionembodying my improved building block;

Fig. 2 is a fragmentary corner sectional detail view of the same;

Fig. 3 is a fragmentary view illustrating the method of tying two of thebuilding block slabs together;

Fig. 4 is a vertical sectional detail View through a suggested wall.

The several objects of my invention are accomplished by the preferredform or" construction shown in the accompanying drawings. In thisconnection my improved building block is indicated at In and comprisestwo sections, an inner section II and an outer section 12. Thesesections H and ii! are each formed of suitable light-weight material andare substantially hollow in construction, providing a top flange l3 anda bottom flange M, with intermediate ribs l5 spaced from each other.Formed in these flanges l3 and M and the ribs l5 in substantialalignment with respect to each other are dovetailed notches !6 which areadapted to receive therein alining l iformed substantially U shapedandof resilient material-whereby when the lin-- ing is inserted toengage the dove-tailed notches it; the side. walls |=8 thereof may besprung to-fit tightly within these notches I 6.

The building block: lll whi'ch-has just previously been described; isintended to be used in that section: of the wall between the corner'portions=- of the building. The corner portions of the building includebuilding blocks l9 which are likewise formed of relatively lightmaterial and comprise an inner section 20 and an outer section 2| withthese sections 20 and 2| provided with dove-tailed notches 22 to receivea lining 23 similar in construction to the lining ll.

When the blocks ID are arranged in the wall of the building as shown inFig. 4, they provide interior air passages 24, with certain passages 25filled with a suitable insulation or other packing 25. The base block 21is mounted upon concrete foundation 28 in the usual manner. The headblock 29 has mounted thereon a sill plate 36 for connection to the roofstructure 3!. A window construction 32 of a standard construction isarranged in the openings 33 provided by the wall.

In building up the wall, the following prescribed steps have been foundeconomical and expeditious:

Th building blocks are arranged, as stated before. upon the concretefoundation 28 with the linings l! engaging the dove-tailed notches l6.Suitable reinforcing bars 34, tied together by tie bars 35, are arrangedwithin these linings H, the adjacent linings forming a completeenclosure, as indicated at 36. These reinforcing bars or rods 34 arelocated in any well known manner and after being properly located andtied together there is then poured into the tubing provided by adjacentlinings H, a concrete filling 31 or the like. As the wall increases inheight, this method is repeated and, by the method, it will be seen thatthe two sections forming the building block ID are substantially tiedtogether in a durable and rigid manner. If found necessary, there may bearranged between each block it suitable reinforcing members or wire mesh38.

Between the horizontal engaging surfaces of the building blocks H1 whenarranged in wall formation there may be arranged a suitable mortar orother cement material. This is also true with reference to the abuttingvertical surfaces.

From the foregoing description, it will be seen that as each slab orsection II and I2 is substantially hollow in construction, the slabs areof relatively light weight; that a very simple and inexpensive methodand means is employed for tying the block sections together and foruniting the block sections into a wall which has a measurable degree ofelasticity whereby to prevent cracking or misplacement of one blockrelative to the other in the event of earth tremors caused byearthquakes. The wall being formed of a material which is termite-proof,is also substantially fireproof, as Well :as soundproof.

While I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification Without departing from the spirit of theinvention. I, therefore, do not wish 15 to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations and modifications as come Within the scope of the appendedclaim.

Having thus described my invention, what I 20 claim as new and desire toprotect by Letters Patent is:

In a building Wall construction, a pair of opposed sections arranged inparallel relation with respect to each other and provided with spaced 35Number ribs extending from their confronting surfaces in parallelhorizontal planes, said ribs being pro- .4 vided with opposed verticallyaligned dovetailed notches, each of said sections having a lining seatedin and conforming to said dovetailed notches, said opposed liningsspanning said ribs and forming an enclosure, and eementitious materialfilling said enclosure and tying said sections together in said parallelrelation.
